An acrylic sheet can make a good table protector because it provides a lightweight, transparent, and customizable surface layer that helps protect furniture from scratches, stains, moisture, and daily wear.

Glass paint can be used on acrylic sheet, but the result depends on paint compatibility, surface preparation, curing conditions, and the final application environment. Acrylic is a smooth and non-porous plastic material, so glass paint may not always bond as effectively as it does on glass.
